With a 3-flute straight-flute geometry and a bottoming chamfer, it cuts threads to the bottom of blind holes and through holes alike. The tap carries a Class 3B fit and an H3 thread limit, targeting close-tolerance internal threads in production and maintenance environments. Overall length is 2.719 inches with a 0.69-inch thread length, keeping the tool compact enough for confined-area work. Licensed machinists, tool-and-die technicians, maintenance mechanics, and millwrights are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe C54510 is suited for blind-hole and through-hole threading operations on a range of ferrous and non-ferrous workpiece materials. Its Series 1003 design covers manual hand-tapping and low-speed machine tapping applications in job shops, maintenance facilities, and manufacturing cells. The bottoming chamfer — typically 1 to 2 threads of lead — allows thread cutting that starts very close to the bottom of a blind hole, making it the correct choice when a spiral-point or plug tap has already been used to start the thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute design provides chip clearance in through-hole and blind-hole work\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright (uncoated) finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H3 thread limit for close-tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, UNC thread form — the standard for inch-series fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Secure the workpiece before tapping and use a proper tap wrench sized for the square drive to maintain alignment and reduce the risk of tap breakage. Apply an appropriate cutting fluid for the workpiece material — cutting oil for steels, a light lubricant or kerosene for aluminum. Back the tap off periodically to break and clear chips, especially in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.719 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51689416524082,"sku":"C54510","price":27.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e16c1442787666475c26f6ccccb6eecd.jpg?v=1788259134","url":"https:\/\/voomisupply.com\/products\/cleveland-c54510-hand-tap-5-16-18-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
